Abstract
An optical communication system ( ), a method ( ) for parallel modulation of an optical spectrum and a method ( ) for parallel demodulation of the optical spectrum of modulated optical frequencies by the system ( ) are described. The optical frequencies are provided in parallel to a modulation section ( ) for modulating with data bits from a data signal source ( ). The data bits are associated with an optical modulator ( ) that controls passage of the optical spectrum at a plurality of predetermined optical frequencies based upon the data bits. The optical frequencies of the optical spectrum, modulated by the data bits, are then transmitted via a communication section ( ) to an optical receiver ( ) that is coupled to a demodulation section ( ) of the system ( ). Modulated optical frequencies are received as a modulated optical spectrum and demodulated in parallel by an optical demodulator ( ) to derive the data bits.
